Wi-Fi logoWi-Fi ( /ˈwaɪfaɪ/, also spelled Wifi or WiFi) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards".[1] However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". A device that can use Wi-Fi (such as a personal computer, video game console, smartphone, tablet, or digital audio player) can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls that block radio waves or as large as many square miles — this is achieved by using multiple overlapping access points. "Wi-Fi" is a trademark of the Wi-Fi Alliance and the brand name for products using the IEEE 802.11 family of standards.

...Case Study: Economic Analysis of Gogo’s In-flight Wi-Fi November 2, 2015 Introduction Gogo pioneered and now dominates the in-flight Wi-Fi business, which allows passengers to access the Internet during their flights. In recent years, consumers have grown from anticipation to dislike towards Gogo’s services due to its steady increase in fees and rapid decrease in speed. Through a dynamic pricing strategy they hope to relieve congestion which indeed have effect, but will not last in the fierce competition of an oligopoly market structure. Unlike its monopolistic position before, Gogo now faces at least three companies—ViaSat, Global Eagle Entertainment, and Panasonic— swiftly eroding its market share with cheaper and faster in-flight Wi-Fi services using satellites instead of antennas. Gogo’s own next-generation technology 2Ku, to come online in 2016, uses satellites that hopefully would achieve better prices with higher speed. To analyze the market for in-flight Wi-Fi and the pricing strategies of Gogo, our paper will discuss five core areas: The price elasticity of demand for Gogo’s service, and how it varies with price levels The market structure Gogo is operating in Its dynamic pricing How the demand for in-flight Wi-Fi has changed over time, technological changes over the past 15-20 years that has affected demand Technological factors that affect supply, how congestion affects pricing and our recommendation Price Elasticity of Demand...

...overview survey of emerging wireless technologies – 802.11(wi-fi), 802.15.4 (Zigbee)and 802.16 (wi-max). WI-FI: Wi-Fi is a popular technology that allows an electronic device to exchange data wirelessly using radio waves over a computer network including high speed internet connections. A device that can use Wi-Fi can connect to a network resource such as the Internet via a wireless networl access point Such an access point has a range of about 20 meters (65 feet) indoors and a greater range outdoors. Wi-Fi works with no physical wired connection between sender and receiver by using radio frequency (RF) technology, a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. The cornerstone of any wireless network is an access point (AP). The primary job of an access point is to broadcast a wireless signal that computers can detect and "tune" into. In order to connect to an access point and join a wireless network, computers and devices must be equipped with wireless network adapters Wi-Fi allows cheaper deployment of local area networks (LANs). Also spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs Manufacturers are building wireless network adapters into most laptops. The price of chipsets for Wi-Fi continues to drop, making it an...

...Developing free Wi-Fi to all of New York City In this report we will be discussing how we would be able to provide free Wi-Fi to New York City and its potential bonus’s and faults for the citizens of New York City. We will be looking at the population, cost and area to be covered. This project would end up costing hundreds of thousands if not up to the millions in man power, energy, and supplies to complete this project. We will also be looking into some of the larger problems that we could encounter in the process of this project, along with the potential good that would come from providing such a hugely used system for free to such a large populous. Defining the Problem Our project can be broken down a couple of ways to help us define the problem better and give us multiple solutions/plans to act upon. A couple things we will need to look at first is the population of New York City. (Roberts, 2011) The census taken in 2010 states that New York City’s population reached a record high of 8,175,133 citizens and only increasing to roughly 8,244,910 citizens in 2011. (Wiki, 2012) (Winslow, 2012). We will also have to look in the total Land area (Square miles of New York City), in 2011 according to latest calculations New York City covered a land total of 302.643 square miles. (Roberts, New York Land Grab, Courtesy of Census, 2011) The cost to complete this project I think would be quite astronomical, from laying all of cable to connect the Wi-Fi devices to having hundreds...

...Wireless Communications Paper Wireless communication involves the transmission of data from one point to another without the need to run cabling in-between. Although it seems relatively new to the end user today, it has surprisingly been around for longer than you may think dating back to the late 1800’s. The first wireless technology discovered was the Radio Frequency (RF signal). Thomas Edison and Nikola Tesla were two inventors that played a huge role in developing the RF technology we still use today. By conducting many experiments using wireless technology they together came up with the RF signal that was first implemented in WWII by the US Military. It wasn’t until the 1970s’ that the first ‘wireless network’ was developed called ALOHAnet. This new wireless network was made to communicate from island to island is Hawaii. Using LAN technologies and a 400 MHz frequency band ALOHAnet was the predecessor of many wireless technologies to come. Today we have many wireless technologies that are used for many different types of services. If you’ve used Bluetooth technology then you’ve used a Personal Area Network (PAN). A PAN network is intended for short ranges and typically controlled and used by a single person. If you’ve connected to the internet at work, a coffee shop, work, or at school then you’ve connected to part of a Wide Area Network (WAN) configured into a Local Area Network (LAN). Most people know a typical WAN by the name of WIFI, even though that’s just a business...

...International agreed to pay a fine of $600,000 as well as adhere to a three year Compliance Plan for illegally interfering and disabling Wi-Fi networks established by it’s customers. In addition to the fine and Compliance agreement, Marriott will also file progress reports to the FCC every three months. The investigation began after a March 2013 complaint from an individual attending a convention at the Marriott Opryland Hotel stating that the hotel was “jamming mobile hotspots so that you can’t use them in the convention space.” Marriott officials stated that they believed that having their employees block Wi-Fi signals and then charging customers to use the hotels plan at a cost of sometimes up to $1,000 was legal in their eyes. According to the official FCC news release this was in direct violation of Section 333 of the Federal Communications Act. Marriott argued that they did this in the best interest of their customers. A company statement from Marriott argued that “Marriott has a strong interest in ensuring that when our guests use our Wi-Fi service, they will be protected from rogue wireless hotspots that can cause degraded service, insidious cyber-attacks and identity theft. Like many other institutions and companies in a wide variety of industries, including hospitals and universities, the Gaylord Opryland protected it’s Wi-Fi network by using FCC authorized equipment provided by well known, reputable manufacturers.” FCC Enforcement Bureau Chief Travis Leblanc...
